what was the 57.92 and 58.62f temps from then?
The 20th century baseline, the 62.03F and 62.45 were from the 1961-1990 baseline.
huh? you said the 1961 to 1990 average was 62.03, so now it's the 20th century 100 year average? what the fk are you trying to say here. It makes absolutely no sense.
NOAA stopped using the 1961-1990 baseline in 1997. The current baseline is the 20th century baseline. CF dishonestly used the 1961-1990 baseline for 1997 and compared it to the 20th century baseline for 2015.
ok so that average temperature is what? 56.92F?
No, the NOAA 20th century global baseline is 57.F. The 57.92F was 1997 using the 20th century baseline and 58.62F was 2015 using the SAME baseline.
